Multiple choice technology programming languages f1(int c) { printf("%d", c); } void main() { int a=1; f1(a++); } 0 1 2 3 Reveal answer Fill a bubble to check yourself B Correct answer Explanation The post-increment operator (a++) passes the current value of 'a' to the function, then increments it afterward. Since 'a' is initialized to 1, the value 1 is passed to f1() and printed. The increment happens after the function call completes.
